Experimental system of closed-loop autonomous navigation under the condition of non-cooperative target

Abstract

The invention provides a test system of closed-loop autonomous navigation under non-cooperative target conditions. The test system comprises: a ground test system used for dynamically simulating a relative distance and angle information between a target satellite and a chaser satellite; a non-cooperative target system used for simulating the relative distance and the angle information between the target satellite and the chaser satellite; a tracer satellite tracking and pointing system used for measuring a relative distance and angle data to the target satellite and outputting the relative distance and the angle data to a tracer satellite GNC system; and the tracer satellite GNC system used for outputting control torque or force to the ground test system according to an autonomous navigation algorithm and the relative distance and the angle data to the target satellite. The test system can guarantee continuity of data to accurately complete closed-loop autonomous navigation test.

Description

technical field [0001] The invention relates to satellite semi-physical test strategy and implementation method, especially the closed-loop autonomous navigation test system when the target is a non-cooperative target and the tracking system is used as an inter-satellite relative position measurement sensor. Background technique [0002] Photoelectric and radar tracking and targeting are two tracking and targeting devices used in space to search, capture, and track non-cooperative targets. They continuously measure the relative angle and distance information between stars and provide them to the GNC subsystem for relative navigation calculations. The basis for subsystem autonomous relative navigation. [0003] Autonomous navigation technology has been widely used in vehicles, navigation, etc., especially in long-range military weapons. However, it is the first case of closed-loop autonomous navigation technology between tracking satellites and non-cooperative target satelli...

AI Technical Summary

Problems solved by technology

However, it is the first case of closed-loop autonomous navigation technology between tracking satellites and non-cooperative target satellites, especially between low-orbit and high-speed moving satellites.

[0004] The performance of the tracking and targeting system and the ability to coordinate and cooperate with the GNC system need to be fully tested and verified on the ground. This kind of test system with the participation of tracking and targeting equipment is the first time in China. The system of the closed-loop autonomous navigation test under the cooperative target conditions has not found descriptions or reports similar to the present invention, and has not yet collected similar data at home and abroad.
